Extended Fuse Ratings

 
 


I am pleased to announce that we have increased the available ratings for several families of fuses.

FCD

The FCD family of fuses are 20 mm long and 5 mm in diameter.  They are fast-acting with a ceramic body and designed to meet European IEC standards (as well as being UL recognized).  The FCD fuse family now extends to 16A up from 10A.

The TSD family of fuses are also 20 mm x 5 mm.  These fuses are a time-delay type (to prevent nuisance tripping when in-rush currents are available) and come with a glass tube body.  The TSD fuses are designed to meet European IEC standards (as well as being UL recognized).  The ratings for the TSD fuse family now range from 50mA to 20A (although agency approvals only go to 16A)
 
Finally, the TCD family now extends to 16A rather than 10A.  Like the TSD above, the TCD is a 5 x 20 mm time-delay fuse, however, the TCD has a ceramic construction as opposed to glass.  The TCD fuse is also designed to meet European IEC specifications.

All of the above fuses are available with or without axial leads.

A cross reference table to Bussmann and Littelfuse is shown below.
